Had a look at settings and review this with some AI tools, and it seems that based on how the desktops work and monitors, there’s no clear way to manage this process, given how you want it to behave. You’re effectively removing the ‘target’ for one of the desktops, therefore, what do you expect the system to do when this happens. I’d thought that you should disable a desktop when you don’t have the tv monitor, but that changes the behaviour. I don’t think there is a sensible fix for what you’re experiencing.
